Simpson and a number of other people were on the roof of the building to look at the Empire State Building, which was lit up in rainbow colors in recognition of a survey that found most Australians support marriage equality, when Simpson swung a woman around, angering her husband, according to police.

Simpson later offered to prove his trustworthiness to the man by playing a game of "trust fall" on an apartment terrace. He went to a ledge and leaned back, but as he grabbed for the man's hand, he slipped and fell to a second-floor landing, police said.

Law enforcement sources told News 4 that Simpson and the others may have been drinking at the time of the accident.
